Four private astronauts are readying for launch to the International Space Station this week while the Expedition 70 crew ramps up microgravity research and maintenance tasks after yesterday’s off-duty day.

The third private astronaut mission to the station, Axiom Mission 3 (Ax-3), is scheduled to liftoff from Launch Complex 39A at NASA’s Kennedy Space Center in Florida at 5:11 p.m. EST Wednesday, Jan. 17. Ax-3 crew members, Commander Michael López-Alegría, Pilot Walter Villadei of Italy, Mission Specialist Alper Gezeravcı of Turkey, and ESA (European Space Agency) project astronaut Marcus Wandt of Sweden, will make the trek to the orbital lab aboard the SpaceX Dragon spacecraft, docking at 5:15 a.m. Friday, Jan. 19. The quartet will spend about two weeks conducting science and research in microgravity before heading home.

Ahead of Ax-3 arrival, NASA Flight Engineer Loral O’Hara spent most of the day prepping station for new visitors. O’Hara inspected the airflow in crew quarters, prepped sleep accommodations for crew occupancy, and cleaned the liners and vents where the four private astronauts will sleep while aboard the orbital outpost.

ESA (European Space Agency) Commander Andreas Mogensen also prepped for Ax-3, completing training for Dragon rendezvous and docking. Afterward, he set up ECHO, which is equipped with motorized probs, for ground teams to perform remote maintenance activities.

While O’Hara and Mogensen prepped for Ax-3 crew arrival, other crew members took to space botany and biology tasks. NASA Flight Engineer Jasmin Moghbeli spent the day working with Plant Habitat-06, thinning wild-type tomato seedlings. Afterward, she set up and installed the Plant Water Management 5 hardware to the Maintenance Work Area.

JAXA (Japan Aerospace Exploration Agency) Flight Engineer Satoshi Furukawa removed culture units from the microscope used for the Space Organogenesis investigation, which demonstrates growth of organ buds from 3D printed human stem cells. Additionally, Furukawa collected water samples from the station’s potable water dispenser for in-flight analysis.

The Roscosmos trio—Flight Engineers Oleg Kononenko, Nikolai Chub, and Konstantin Borisov—performed an array of maintenance activities on Tuesday. Kononenko replaced hardware in the Zvezda service module, while Chub replaced the thermal control system pump panel in the Zarya module. Afterward, Chub conducted an experiment studying liquid phases in microgravity, while Borisov distilled samples from the Roscosmos segment water management system and conducted maintenance on the station’s vacuum cleaner.

Station Wraps Busy Week Before Cygnus Cargo Mission Launches

Image
This high exposure photograph from the International Space Station shows Earth’s atmospheric glow and a starry sky as the orbital complex soared above the Pacific Ocean. The Expedition 70 crew is looking ahead to the arrival of a U.S. cargo craft due to arrive at the International Space Station next week. Meanwhile, the Axiom Space 3 (Ax-3) crew finished its first week in orbit with a busy schedule of research, education, and media activities. Northrop Grumman’s Cygnus cargo craft will take its first ride atop a SpaceX Falcon 9 rocket when it lifts off at 12:29 p.m. EST on Monday from Kennedy Space Center in Florida. The private space freighter will be carrying over 8,200 pounds of science experiments, crew supplies, and lab hardware to the orbiting outpost. NASA Flight Engineer Jasmin Moghbeli is due to capture Cygnus with the Canadarm 2 robotic arm at 3:35 a.m. on Wednesday. She will be on duty that morning along with fellow NASA astronaut Loral O’Hara who will monitor Cygn...

NASA and Sierra Space are making progress on the first flight of the company’s Dream Chaser spacecraft to the International Space Station. The uncrewed cargo spaceplane is planned to launch its demonstration mission in 2024 to the orbital complex as part of NASA’s commercial resupply services. Credit: Sierra Space/Shay Saldana NASA and Sierra Space are preparing for the first flight of the company’s Dream Chaser spacecraft to the International Space Station. Dream Chaser and its companion cargo module, called Shooting Star, arrived at NASA’s Neil Armstrong Test Facility in Sandusky, Ohio, for environmental testing, scheduled to start in mid-December, ahead of its first flight, scheduled for the first half of 2024. The Neil Armstrong Test Facility, part of NASA’s Glenn Research Center in Cleveland, is home to multiple test facilities, including the Space Environments Complex and the In-Space Propulsion Facility, both stops for Dream Chaser. The complex is home to the Mechanical Vib...

Crew Dragon Suit Checks as Station Begins Orbital Reboosts

Image
This long-exposure photograph from the space station reveals the Milky Way glittering above a bright but exaggerated atmospheric glow blanketing the Earth’s horizon. The Expedition 63 crew checked out SpaceX Crew Dragon suits today and stayed busy with a full slate of space research. The International Space Station also completed the first of three orbital reboosts to get ready for the next crew mission in October. Flight Engineers Doug Hurley and Bob Behnken inspected the suits they will wear when they return to Earth aboard the Crew Dragon spaceship. The duo tried on their suits for a fit check and ensured the components are in good condition. They are scheduled to depart the station on Saturday and splashdown the following day. NASA TV will cover all the departure activities live. The homebound-duo started the day replacing environmental control system (ECS) hardware aboard the orbiting lab. That work required temporarily removing a plant habitat from the Unity module to...
